I word originating in the 1980s in NC. Initally a nickname many people called a guy from Jacksonville NC. Use of the word originally was used to describe his feats of strength in the gym. Many people thought it had to do with his sexual aura,so the word has overtime developed a second meaning to refer to a mans vitality.
1) That guy is cockstrong! Did you see him lift the back end of that car?!

2) So much sex last night, glad I am cockstrong.
